HEATER FOR RAILROAD-CARS.

Specification of Letters Patent No. 30,753, dated November 2'7, 1860.

To all whom it may concern:

Be it known that I, W. PAULI, of the city of Alexandria and county of Alexandria and State of Virginia, have invented certain new and useful Improvements in Stoves or Heaters for Railroad-Cars, &c.; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification.

Figure l is a top view, and Fig. 2, an elevation in section.

The object of this improvement is to overcome the objections to the stoves now in use in railroad cars, and by distributing the heat at the ends or near the doors to render them more comfortable; by so constructing and arranging the heater, that it may be suspended below the floor of the car, without danger of burning, and by allowing the heat to pass either into the car by an upper register on the extension pipe from the heater, or to escape by a lower register on the same, the temperature of the car may be completely under control. The space occupied by the ordinary stoves in each car, and the annoyance from heat to the passengers in its immediate proximity renders a practical furnace or heater a desirable object.

The heater consists of a fire box A with suitable grate bars and ash pan; around A is a chamber B B in which is placed the smoke pipe E which passing horizontally out of the side of the heater may be carried vertically outside of the car. This chamber furnishes the heat for the ends of the car. Above the tire box is a close plate forming the bottom of the chamber 0, 0. This chamber 0 being interposed between the fire box A, and detached from the floor of the car, effectually prevents danger from fire.

H is the floor of the car.

F is a large sized tube connecting the chamber 0, with the car. It is furnished with a register in the floor.

(a a) are holes for the ingress or egress of air into chamber a.

G, is a smaller pipe passing through F into the fire box A. It has a long hollow stopper, which may be packed with a nonconducting substance to prevent the cap of the stopper becoming unduly heated. It is through this tube the fire box is supplied with fuel.

D D are upright tubes connected by horizontal ones with the chamber B. They have registers e at their upper, and register f at their lower ends.

Z), is a rod connecting the upper and lower registers which are so arranged, that on the opening of one the other will be closed.

The control of the heat from this furnace is readily accomplished. When the temperature in the cars is sufficiently raised, the upper registers at the ends of the car may be closed. The connecting rods Z), opening the lower registers allows the heat to escape. If the center register Fis also closed the heat will escape by the openings The manner of suspending the heater from the car will readily occur to the mind of the mechanic and a small space between the top plate of chamber 0, and the floor, will prevent danger from the heat, thus rendering an economical and efficient furnace for heating railroad cars.

l Vith some slight modification in the tubes, &c the heater may be applied to dwellings.

Having described my improvement what I claim as my invention and desire to secure by Letters Patent is The arrangement of a heater provided with an upper chamber C, above the fire box A, side chamber B, smoke pipe E, tubes F when employed with tubes D D provided with upper and lower registers and rods 7),, I), operating substantially in the manner and for the purpose of heating railroad cars.

In testimony whereof I have signed my name before two subscribing witnesses.

WM. PAULI.
